The Fly Tying Material Database Search utility is an recent addition to the Diptera site. All you need to do is type in a list of materials seperated by spaces and then click search. A list of fly patterns will be returned that meet the criteria entered and includes the materials required for tying each of them..
If Pheasant Tail Peacock Herl Fine Red Wire was typed and the Search button clicked it would more than likely return the Cruncher pattern due to this pattern containing all those materials.
If Yellow Black Chenille was entered then more than likely Bitch Creek Nymph and Yellow Montana fly patterns would be returned due to this pattern containing all those materials.
